The England striker believes his compatriot, and captain at Liverpool, remains one of the best players on the planet and is looking forward to playing alongside him at club level
The 32-year-old secured an emotional return to Liverpool from Southampton earlier this summer, before heading to Brazil with England for the World Cup, where he is also captained by Gerrard.

He told the club's official website: "He's still one of our best players - still world-class, in my opinion. As a deep-lying midfielder he's one of the best.
"And he's good off the field too - not one to shout.
"He does his actions on the pitch and he speaks to the young lads and puts an arm around them when it's needed.
"It was top drawer the way he walked off with Raheem Sterling when Raheem was sent off against Ecuador. The young lads aren't intimidated and he's one of the main reasons for that."
Gerrard has hinted that the Brazil showpiece could be his last tournament with England, but Lambert has backed him to extend his international career beyond the South American showpiece.
"Whatever decision he makes everyone is going to be behind him and respectful of it," added the former Southampton man.
"But, if you are asking my opinion, I think he can go on for a number of years."
